Computer starts but no video

January 27, 2006 at 06:44:37
Specs: XP, Different on all 3

I am having the same problem; on three different computers. The computer acts like it is powered on, but not completely. Almost like it is standby. No video. I have changed the video card on all three machines, but still not working. The power button will not power the computer down. I have had to completely unplug the thing just to get it to turn off.

I get nothing. The monitor continues to do a self-check. I've tried different monitors and different video cards. I find it strange that three computers (different brands, same OS) are having the same issue.

Is the monitor power indicator light green in color. That means its getting a signal.

No, the indicator is still red on each different monitor.

I noticed in this forum that there are a lot of people having this same sort of issue. Is there some new virus out and about that could have caused this to happen?

No. To be quite honest with you I am a school teacher. I teach a tech support class and we accept work from our community. All three of these machines are from individuals outside the school (three different towns to be exact). They brought them to my class to troubleshoot their problems. I'm not sure what happened to them before they got here. We tried everything I have stated above to correct the problem, but to no avail.

I thought maybe an "expert" could help me out and give me an answer. I definitely do not qualify.

It has to be the strangest thing I've ever seen, so I automatically assumed it was a virus. I just can't find any new viruses that have had this effect.

Well my guess would be either a power surge,they have been dropped or banged ,or just died,
Have you tried a different monitor that you know works on this computer?
If so did it work?

We have to keep asking questions to get information. Maybe we are getting somewhere. No mention of checking BIOS for abnormalities ??

Look for leaking or bulging capacitors on the motherboard. Some pictures--

I can't get into the BIOS. The computer powers up into what seems like standby. Not full power. There is nothing on monitor. Nothing. The monitor does not even receive a signal from computer.

We have changed monitors with known working monitors. We have changed video cards with known working cards.

I understand you need to keep asking questions. Eventually, the right one will be asked and it will help my class correct the problem. I don't mind answering your questions. Anything for free help :)

I have not checked for leaking or bulging capacitors, but will do so today. Is this possible that it would happen on three machines in three different locations during the same period of time?

I am no expert, but sometimes one statement made
can tick with me for reply. I had one person come back a week later, and create a special thank you Post to me, after he was forgotten.
Good to see that you take an active part of your Post. Some do not.

No telling what people at other places have done
with there computers. Like they could have been inside the box, and Static electricity from their body can ruin the electronic components in computers.

OK. Well, I'll let these problems go for now, but will keep on the lookout for a solution. Thank you for sharing your knowledge and ideas with me.

There are three other posts quite similar to mine.

I can understand the probability of a failing PSU as the cause for one PC buttt here the issue is three PC's...

Don't forget though, this is a process of elimination suggestion, furthermore these are all three machines from individuals outside the school (three different towns to be exact).
